What is Heat Exchanger? - Complete Explanation

Recuperative Heat Exchangers VS Regenerative heat exchangers. Recuperators are the one in which two fluids are separated all the time either direct or in indirect contact (through a solid barrier) to each other. A recuperator is a countercurrent flow heat recovery heat exchanger positioned within the supply in order to recover the waste heat.

Waste Heat Recovery Devices – IspatGuru

The radiation recuperator gets its name from the fact that a substantial portion of the heat transfer from the hot gases to the surface of the inner tube takes place by radiative heat transfer. The cold air in the outer shell, however, is almost transparent to infrared radiation so that only convection heat transfer takes place to the incoming air.
